Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

A new improved procedure is proposed for studying critical temperature phase transformations in high-strength lowalloy steels and their welded joints, which consists in approximation of the dependence of thermal expansion factor on temperature and separation of structural transformation from thermal expansion. For detailed determination of the features of transformations in the metal of welds of high-strength low-alloy steels it is proposed to use kinetic parameters of transformation: volume effect of transformation (S), maximum value of transformation intensity (Vmax), temperature of maximum intensity of transformations (TV).
